I think this picture really puts into perspective the silly mental games we play when it come to dick size. A woman’s Vagina is on average only 4″ deep, so even us small guys can rock her world if we do it right. Even if she lowers the ruler a bit to make it line up better with the entrance to her vagina, you can see clearly that us small guys can go pretty deep too. The tape measure is displaying inches, just so you understand. Just in case you might think this woman is short or small, she is in fact five feet eight tall.
